Abstract
        The formation of multiple transmission peaks with flat-top shapes in photonic crystals with a super-lattice structure is 
presented. By reducing the confinement strength from the barriers, the photon quantized states within each mini-bands of 
super-lattice structures can be coupled to each other, and multiple transmission peaks with flat-top shapes are formed. The 
performance of these flat-top transmission peaks is investigated in detail, and the formula to determine the frequency 
locations of these peaks is presented. These results may facilitate the potential applications of multiple channeled filtering 
based on photonic hetero-structures.
